I don't know if this was discussed in the past, so forgive me if so 😔
Would it be possible to add a feature that links a new arrival/change of an existing one/discussion to a member's interest?
To clarify: let's say I collect UK circulating commemorative coins (CATEGORY) or birds on coins (TAG). I mark these as my field of interest and every time a new coin is added or an existing one changed, the system sends me a notification (similar to discussion topics you participate in).
